摘 要:采用42tex气流纺和19.5tex紧密纺纱线,对不同混纺比例的中空涤/可持续棉纱线进行条干、毛羽、力学性能测试,并采用主成分分析法和灰色关联度分析法对测试结果进行分析。主成分分析结果表明:在评估中空涤/可持续棉混纺纱性能优劣时,U值、粗节35%、粗节50%可作为评价条干性能的主要指标;Hmax1m、Hmax3m、Hmax10m可作为评价毛羽性能的主要指标;断裂强度和断裂伸长可作为评价力学性能的主要指标。灰色关联度分析结果表明:在评估纱线综合性能优劣时可以优先评估纱线条干指标,其次是纱线强力和毛羽指标;19.5tex紧密纺的综合性能优于42tex气流纺,且混纺纱的综合性能随着可持续棉含量的增加而下降。

Abstract: 42 tex air-spun yarn and 19.5 tex compact-spun yarn are used to test the evenness, hairiness and mechanical properties of hollow polyester/sustainable cotton yarn blended with different blending ratios, and the test results are analyzed through principal component analysis and grey relational analysis. The results of principal component analysis show that when evaluating the performance of the blended yarn of hollow polyester and sustainable cotton, the U value, a thick section of 35% and a thick section of 50% can be used as the main indicators to evaluate evenness. Hmax1m, Hmax3m and Hmax10m can be used as the main indicators to evaluate hairiness. Breaking tenacity and elongation at break can be used as the main indicators to evaluate mechanical properties. The results of grey relational analysis indicated that when evaluating the comprehensive performance of the yarn, the evenness of yarn can be evaluated first, followed by the strength and hairiness of yarn. The comprehensive performance of 19.5 tex compact-spun yarn is better than 42 tex air-spun yarn, and the comprehensive performance of blended yarn decreases with the increase of content of sustainable cotton.

Key words: hollow polyester; sustainable cotton; principal component analysis; grey relational analysis; compact-spun; evenness

可持续棉纤维又称为瑞优棉纤维,采用可持续的方式进行生产,目前,许多纺织品产业对环保的重视程度日益提高,可持续棉的应用市场必将日益扩大。将可持续棉与中空涤纶纤维进行混纺由此可开发出生态友好型的混纺纱线,可广泛应用于保暖内衣,袜子等。中空涤纶纤维在保暖行业的应用日益广泛,中空涤纶纤维中包含大量的静止空气,能为织物带来轻质弹性、良好透湿性以及舒适的保暖效果,因中空部分的毛细管的作用而使吸水性和透水性良好,因此用中空纤维制作的衣料穿着舒适,具有吸湿、透气的特点[1-3]。……
